Résumé : | Objectives To investigate the effects of exoskeleton-assisted gait training in stroke patients. Design Prospective randomized controlled trial. Setting Rehabilitation department in a single tertiary hospital. Participants Thirty (N=30) chronic stroke patients with Functional Ambulatory Category scale (FAC) between 2 and 4. Intervention Patients were randomly assigned to 1 of 2 groups: training with Healbot G, a wearable powered exoskeleton (Healbot G group; n=15), or treadmill training (control group; n=15). All participants received 30 minutes of training, 10 times per week, for 4 weeks. Outcome Measurements The primary outcome was oxyhemoglobin level changes, representing cortical activity in both motor cortices using functional near-infrared spectroscopy. The secondary outcomes included FAC, Berg Balance Scale, Motricity Index for the lower extremities (MI-Lower), 10-meter walk test, and gait symmetry ratio (spatial step and temporal symmetry ratio). Results Compared to the control group, during the entire training session, the pre-training and post-training mean cortical activity, and the amount of increment between pre- and post-training were significantly higher in the Healbot G group (?mean?+?SD; pre-training, 0.245+0.119, post-training, 0.697+0.429, between pre- and post-training, 0.471+0.401?mol, P<.001 there was no significant difference in cortical activity between affected- and unaffected hemispheres after healbot g training. fac p=".012)," mi-lower spatial step gait symmetry ratio were improved significantly the group. conclusion exoskeleton-assisted training induces modulation effect both motor cortices a balanced activation pattern with improvements walking ability voluntary strength.> |
